he does not have any blisters whatsoever, there is no redness or anything to signify a burn of any sort, it is just his scales without the shiny part, there has been no bleeding, no blood on the substrate or on him and the soft-ish part underneath looks wrinkly now that i look more closely, does the underbelly shed a seperate layer off before the full shed? my friend has told me hes probably just shedding or it could be a rash. i use repti-bark as the substrate.
